Water, Sanitation and Hygiene (WASH) is an essential part of the development process. Sound PFM supports aggregate control, prioritization, accountability and efficiency in the management of public resources and delivery of services, which are critical to the achievement of public policy objectives, including achievement of the Millennium Development Goals (MDGs). In addition, sound public financial management systems are fundamental to the appropriate use and effectiveness of donor assistance since aid is increasingly provided through modalities that rely on well-functioning systems for budget development, execution and control. These principles are reflected in the Strengthened Approach document, which has been developed by the World Bank in consultation with the PEFA partners, and with the OECD DAC Joint Venture on Public Financial Management. PFM work should be weighted toward supporting PFM reform implementation reforms and capacity building rather than detailed diagnostic analysis, should add value to Government budget and reform processes.
